Let us denote this dg-category by DGM-$\mathcal{C}$.

WebGiven A an abelian category, we denote by D.A/the derived category of A and we denote by Da.A/the full subcategory of objects with cohomology vanishing in degrees >a. Let Abe a differential graded (=dg) algebra. We denote by D.A/the derived category of dg A-modules and by A-perf the category of perfect complexes, i.e.,the Web7 hours ago · Category theory, while a mathematical topic, is typically not covered in undergraduate or even graduate math programs, at least not directly. Described sometimes as “the mathematics of mathematics,” its goal is to formalize how mathematical objects are related to each other. ...

WebOrlov studied the derived category and the category of singularities of such an algebras in great detail in [21], and much of the technique of the proof of Theorem 1.1 derives from that paper.

WebJun 17, 2016 · $\begingroup$ This might be overly pedantic, but to get the right $\infty$-category of quasicoherent sheaves I think you need to take the limit of the cosimplicial diagram that takes all the iterated intersections into account, rather than just an equalizer. (This is a general theme in passing from 1-categories to $\infty$-categories. In a sense … WebAug 9, 2024 · While the derived category of mixed motives can also be defined with integral rather than rational coefficients, Voevodksy observed that the derived category of integral motives cannot have a motivic t-structure (Voevodsky, Prop. 4.3.8). Thus, the abelian category of motives always refers to motives with rational coefficients. References
